Hi, I bought my macbook used about 6months ago now, it had a brand new battery in it nearly had only about 40 cycles. Now that school is out for the summer, i just dont tend to use the macbook every day like i do during school. The problem i seem to have is that when I let the macbook sit (turned off) and turn it back on the battery life has dropped a few percent.. Now i havnt used the mac in a few days and i just sat down and i realized my battery life dropped to 94% while it was off.. I might be imagining things and totally forgot that last time i used it the battery life wasnt fully charged but im almost sure it was fully charged last time i used it and then shut it off. Any ideas why this could be happening?
